Case Quick Facts
Patient Background
Personal and Social History
Ms. Ananya Sinha was a 35-year-old home-based craft worker residing in Patna, Bihar. She was married, and her primary caregiver was her husband, Mr. Abhishek Sinha. Her sister, Ms. Riya Sinha, served as the secondary caregiver, providing additional support during periods of increased need.
Ananya’s occupation involved detailed handcraft work performed at home. This work required reasonable visual acuity and manual dexterity, both of which were affected by her underlying condition. Her work was an important source of personal satisfaction and contributed to the household income, making functional preservation a meaningful goal of her care.
She lived with Hermansky-Pudlak syndrome (HPS), a rare inherited disorder that she had been diagnosed with during earlier evaluations. Her family had developed an understanding of the condition over the years and had learned to take additional precautions around injuries and bleeding. However, the recent bleeding episode highlighted gaps in their preparedness for more significant bleeding events.
Baseline Functional Status Before Hospitalization
Before the hospitalization, Ananya was functionally independent in most basic activities of daily living. She could feed, dress, bathe, groom, and use the toilet without assistance. She walked independently within familiar environments and performed simple craft activities that did not require fine visual detail.
However, she already had established limitations. Her reduced visual acuity meant she needed additional time and effort for tasks requiring detailed vision. She used protective sunglasses outdoors because of photophobia. She avoided walking alone at night or in unfamiliar areas. Her family was aware that she bruised easily and took longer to stop bleeding after minor cuts.
These baseline limitations were well-accepted by the family and had been incorporated into their daily routine. The challenge arose when a seemingly minor oral injury led to persistent bleeding that exceeded what the family could manage at home.
Clinical Context: Hermansky-Pudlak syndrome is not a single disease but a group of rare autosomal recessive disorders caused by mutations in genes affecting lysosome-related organelles. The condition is particularly relevant in certain populations, including Puerto Rican individuals, but occurs worldwide. In India, it remains under-recognized, which can delay diagnosis and appropriate precautions.
Reason for Hospitalization
Ananya accidentally injured the inside of her mouth, likely during eating. While such minor oral injuries typically resolve quickly in individuals without bleeding disorders, in her case, the bleeding persisted beyond what the family could manage with local pressure.
Over the following hours and days, she developed:
- Persistent oral bleeding that did not respond adequately to home measures
- Progressive fatigue related to ongoing blood loss
- Light-headedness particularly when standing, suggesting reduced circulating volume
- Reduced appetite and general weakness
The family sought hospital care after recognizing that the bleeding was not stopping and her general condition was deteriorating. She was admitted for a total of 5 days, during which the hospital team assessed her hemoglobin, platelet count, bleeding history, vital signs, hydration status, vision-related functional limitations, and medication history.
Clinical Diagnosis and Findings
Primary Diagnosis: Hermansky-Pudlak Syndrome
Hermansky-Pudlak syndrome is a group of rare inherited disorders affecting intracellular organelles in several cell types. The condition results from defects in genes responsible for the formation and function of lysosome-related organelles, which include platelet dense granules and melanosomes.
The important clinical features relevant to Ananya’s presentation included:
- Platelet storage-pool dysfunction — The platelets lack adequate dense granules, which contain adenosine diphosphate (ADP) and serotonin, substances critical for normal platelet aggregation and clot formation. This means that even when the platelet count appears normal or near-normal on a complete blood count, the functional ability of platelets to form stable clots is significantly impaired.
- Oculocutaneous hypopigmentation — Ananya had lighter pigmentation of her skin and hair compared with her unaffected relatives, a consequence of melanosome dysfunction.
- Visual impairment — Reduced visual acuity, nystagmus, and light sensitivity resulting from macular hypopigmentation and abnormal retinal development.
It is important to note that certain HPS subtypes can also involve progressive pulmonary fibrosis, inflammatory bowel disease, or kidney disease. Ananya’s documented assessment did not indicate known chronic kidney disease, diabetes, or pulmonary complications at the time of this care episode, though ongoing monitoring for subtype-specific complications remained part of her long-term management plan.
Associated Conditions at Presentation
Oculocutaneous Hypopigmentation
Lighter skin and hair pigmentation compared to unaffected family members. This is a visible marker of the underlying melanosome dysfunction but does not itself require treatment.
Reduced Visual Acuity
Impaired vision requiring regular ophthalmological assessment. Affected reading small print, identifying small objects, and navigating unfamiliar environments.
Photophobia
Bright sunlight caused significant discomfort, necessitating protective sunglasses outdoors and careful management of indoor lighting.
Mild Anemia After Bleeding
Hemoglobin decreased following the recent oral bleeding episode, contributing to fatigue and light-headedness. Required hematological follow-up.
Initial Home Assessment — Clinical Parameters
Recorded at the first home visit after hospital discharge. No active bleeding was present at this assessment.
| Clinical Parameter | Finding | Interpretation |
|---|---|---|
| Blood Pressure | 112/72 mmHg | Within normal range |
| Heart Rate | 84 beats/min | Normal; mild tachycardia not present |
| Respiratory Rate | 17/min | Normal |
| Temperature | 98.1°F | Afebrile |
| Oxygen Saturation | 98% on room air | Normal; no respiratory compromise |
| General Condition | Stable | Alert, comfortable, no acute distress |
| Active Bleeding | None | Oral bleeding had resolved before discharge |
CLINICAL REASONING
Why Bleeding Occurs Despite Normal Platelet Counts
A critical point in understanding HPS is that the bleeding tendency is not primarily due to a low platelet count (thrombocytopenia). Instead, it results from platelet dysfunction — specifically, the absence or deficiency of dense granules within the platelets. These granules normally store ADP, calcium, and serotonin, which are released during platelet activation to promote aggregation and stable clot formation. Without these granules, the initial platelet plug forms but is unstable, leading to prolonged bleeding even from minor injuries. This is why a routine complete blood count may show a normal platelet number, yet the patient bleeds abnormally. Specialized tests such as platelet aggregation studies or electron microscopy of platelets are typically required to confirm the functional defect.
Hospital Course and Discharge
Ananya was hospitalized for 5 days. During this period, the hospital team provided the following management:
Bleeding Control
The persistent oral bleeding was managed with appropriate medical interventions. The exact measures were directed by the treating team and documented in the hospital records.
Blood Count Monitoring
Hemoglobin and platelet counts were monitored to assess the impact of blood loss and guide further management. The mild anemia that developed was noted and tracked.
Hydration and Supportive Care
Intravenous fluids and supportive measures were provided as needed to address the effects of blood loss, including fatigue and light-headedness.
Specialist Consultations
Hematology and ophthalmology inputs were obtained to plan the post-discharge period, including bleeding precautions and visual support strategies.
Discharge Plan
Ananya was discharged once the bleeding had stopped and her clinical condition was stable. Her discharge plan included several components that directly informed the subsequent home healthcare program:
- Specialist-directed bleeding precautions to prevent recurrence
- Comprehensive medication review with instructions to avoid medications that could increase bleeding unless specifically approved
- Scheduled hematology follow-up for ongoing blood count monitoring
- Ophthalmology follow-up for continued visual assessment
- Nutritional guidance to support recovery from anemia
- Injury-prevention measures for the home environment
Key Instruction: The family was specifically instructed to avoid medications that could increase bleeding — including over-the-counter pain relievers such as aspirin and ibuprofen — unless explicitly approved by the treating clinician. This is a critical safety measure for patients with platelet dysfunction.
Why Home Healthcare Was Clinically Appropriate
CLINICAL REASONING
Medical Justification for Home-Based Care
After discharge, Ananya did not require the intensive monitoring or interventions that would necessitate continued hospitalization. Her vital signs were stable, the bleeding had resolved, and she was able to perform basic self-care. However, several factors made professional home healthcare services the most clinically appropriate next step:
- Residual fatigue and anemia: She needed monitoring for ongoing fatigue, appetite, and signs of further blood loss while her hemoglobin recovered under medical supervision.
- Anxiety about bleeding: Following the hospitalization, Ananya had significant anxiety about accidental injuries and recurrent bleeding. A professional home nurse could provide structured reassurance and teach the family evidence-based bleeding response measures.
- Vision-related safety gaps: Navigating the home environment safely with reduced visual acuity and photophobia required environmental modifications and adaptive strategies that a trained home care team could help implement.
- Medication safety: Ensuring that no inappropriate medications were being taken and that prescribed medications were administered correctly required ongoing supervision.
- Coordination of specialist follow-up: Hematology and ophthalmology appointments needed to be tracked and adhered to, which is a recognized strength of structured post-hospital discharge care.
Patient Safety
Daily bleeding checks, bruising documentation, and environmental hazard identification reduced the risk of a second significant bleeding episode.
Comfort and Familiarity
Recovering at home allowed Ananya to stay in a familiar environment, particularly important given her vision-related difficulty with unfamiliar settings.
Functional Rehabilitation
Gentle physiotherapy and graded activity helped rebuild stamina lost during the bleeding episode and hospitalization without introducing injury risk.
Family Education and Support
Structured teaching sessions equipped the family with the knowledge to manage daily care confidently and recognize warning signs early.
Home Care Plan by AtHomeCare Patna
The home healthcare program was designed around six core pillars: bleeding precautions, injury prevention, vision-related safety, medication adherence, nutritional support, and functional independence. Each pillar was addressed through specific interventions delivered by the patient care team.
Home Nursing
Skilled nursing interventions by trained specialized nurses in Patna
The home nurse played a central role in Ananya’s daily care. Unlike untrained domestic help, a qualified nurse brings the ability to recognize subtle clinical changes, perform structured assessments, and communicate effectively with the treating physicians. This distinction is particularly important in a condition like HPS, where early detection of bleeding can prevent a life-threatening emergency.
Vital Signs Monitoring
Blood pressure, heart rate, respiratory rate, temperature, and oxygen saturation recorded daily. Particular attention to trends suggesting ongoing blood loss or recovery.
Bleeding Surveillance
Systematic checks for nosebleeds, gum bleeding, unusual bruising, blood in urine or stool, and prolonged bleeding from minor injuries. Every episode documented.
Fatigue and Activity Monitoring
Daily assessment of energy levels, appetite, and activity tolerance. Changes documented and correlated with hemoglobin recovery trajectory from laboratory follow-up.
Medication Adherence Review
Verification that prescribed medications were taken correctly. Screening for any over-the-counter medications that could increase bleeding risk. Coordination with 24×7 pharmacy services for timely refills.
Bleeding Precaution Reinforcement
Daily reinforcement of safe practices including gentle oral hygiene, avoidance of sharp objects, and proper wound care techniques for minor injuries.
Laboratory Appointment Tracking
Blood tests were performed according to the hematologist’s schedule rather than being independently interpreted by the home team. The nurse ensured appointments were kept and results communicated.
Patient Attendant Services
Non-medical assistance for daily functioning and safety
While the nurse handled clinical assessments and medical tasks, the patient attendant provided practical daily support:
- Grocery shopping and outdoor errands — Ananya’s photophobia and reduced visual acuity made navigating markets independently challenging.
- Transportation assistance — Accompanying Ananya to medical appointments, ensuring safe travel.
- Heavy household tasks — Tasks involving lifting, reaching, or potential contact with sharp edges were handled by the attendant.
- Safety during unfamiliar environments — Providing physical guidance and verbal cues when navigating unfamiliar areas.
Physiotherapy at Home
Conditioning and safe mobility restoration
Ananya did not have major motor impairment. Her mobility limitations were primarily related to deconditioning from the hospitalization and bleeding episode, combined with vision-related caution. The physiotherapy program at home was designed with specific principles:
Key Principle: Activities with unnecessary injury risk were deliberately avoided. No high-impact exercises, no rapid direction changes, no heavy or sharp equipment, and no exercises that could lead to falls. The role of physiotherapy here was gradual reconditioning within safe boundaries.
| Treatment Goal | Intervention | Rationale |
|---|---|---|
| Maintain strength | Gentle strengthening exercises | Prevent further deconditioning without straining |
| Improve endurance | Gradual walking progression | Systematically increase distance as stamina improved |
| Reduce deconditioning | Sit-to-stand exercises | Functional movement pattern relevant to daily transfers |
| Improve confidence | Balance exercises (supervised) | Address cautious gait related to vision concerns |
| Maintain flexibility | Light stretching | Prevent stiffness from reduced activity |
| Functional activity | Simulated daily tasks | Practice craft-related movements safely |
Nutritional Support
Dietary guidance for anemia recovery and overall health
After a bleeding episode resulting in mild anemia, nutritional support plays an important role. The home care team, with input from the dietitian consultation service, focused on:
- Iron-rich foods to support hemoglobin recovery under the hematologist’s guidance
- Adequate protein intake for tissue repair and muscle recovery
- Consistent hydration monitoring, particularly important given the fluid loss associated with bleeding
- Vitamin C-rich foods to support iron absorption
- Regular monitoring of appetite and dietary intake, with any persistent reduction reported to the treating physician
Equipment and Home Adaptations
The home setup included both clinical monitoring equipment and safety adaptations. Some items were arranged through medical equipment rental in Patna.
Disease-Specific Assessment
Bleeding Assessment Protocol
The home nurse conducted a systematic bleeding assessment at each visit. This level of systematic monitoring is a key difference between specialized nursing services in Patna and untrained home care.
| Bleeding Site | What Was Checked | Frequency |
|---|---|---|
| Nose (Epistaxis) | Active bleeding, dried blood, frequency of nosebleeds | Daily |
| Gums (Gingival) | Spontaneous bleeding, bleeding during brushing | Daily |
| Skin (Bruising) | New bruises, size progression, location, color changes | Daily, documented |
| Minor Injuries | Duration of bleeding from cuts or scrapes | As they occur |
| Urinary (Hematuria) | Urine color changes, reported by patient | Daily questioning |
| Gastrointestinal | Stool color (black/tarry), vomiting blood | Daily questioning |
| Menstrual | Heaviness and duration when applicable | During menstrual periods |
Patient Education Component: Ananya was taught to report any unusual or persistent bleeding promptly. She was educated about what constitutes “unusual” in the context of her baseline — for example, a nosebleed lasting more than 10 minutes, a bruise appearing without known trauma, or any bleeding that did not stop with applied pressure within a reasonable timeframe.
Functional Vision Assessment
The home team did not perform formal ophthalmological testing — that remained the responsibility of Ananya’s ophthalmologist. Instead, the home assessment focused on the functional impact of her visual impairment:
Identified Difficulties
- • Reading small print in instructions or labels
- • Identifying small objects on work surfaces
- • Walking safely in unfamiliar areas
- • Working in low-light conditions
- • Distinguishing objects with poor contrast
Implemented Adaptations
- • Improved home lighting in all work areas
- • Large-print labels on medications and supplies
- • High-contrast markings on steps and edges
- • Protective sunglasses for outdoor use
- • Organized household items in fixed locations
These adaptations draw from established principles of creating a safe home environment for individuals with sensory limitations, adapted specifically for the needs of a younger patient with HPS-related visual impairment.
Home Environment Safety Review
The family, guided by the home care team, conducted a thorough review. This fall and injury prevention assessment was tailored to address both bleeding risk and vision-related hazards:
Functional Assessment
Baseline Functional Status at Start of Home Care
| Domain | Status | Details |
|---|---|---|
| Mobility | Independent walking | Approximately 210 metres; needed extra time in unfamiliar environments |
| Outdoor Mobility | Required assistance | Used sunglasses outdoors; avoided walking alone at night |
| Bed/Chair/Toilet Transfers | Independent | No difficulty with any transfers |
| Feeding/Dressing/Bathing/Grooming | Independent | Self-managed; precautions in place for slip prevention |
| Detailed Vision Tasks | Required Assistance | Reading small print, identifying small objects |
| Sharp Tool Tasks | Required Assistance | Craft work involving cutting tools handled with help |
| Simple Craft Activities | Independent | Activities not requiring fine visual detail |
Daily Care Plan
A structured daily routine provided predictability and reduced anxiety. Each time block had specific clinical and functional objectives.
Morning Routine
- Medication administration
- Bleeding and bruising check
- Nutritious breakfast
- Gentle stretching session
- Short supervised walk
- Vision-friendly household activities
Afternoon Routine
- Balanced lunch
- Rest period
- Light craft work (adapted)

Risks Monitored and Escalation Criteria
Ongoing Risk Surveillance
Recognizing early warning signs is a fundamental competency in home healthcare. For a patient with HPS, the risk profile is distinct:
Prolonged Bleeding
Any bleeding not stopping with standard first-aid measures within expected timeframe
Nosebleeds
New or recurrent epistaxis, particularly if lasting more than 10 minutes
Gum Bleeding
Spontaneous or prolonged gingival bleeding
Significant Bruising
Large, expanding, or unexplained bruises
Anemia-Related Fatigue
Worsening tiredness suggesting possible further blood loss
Dizziness and Falls
Orthostatic dizziness or any fall event requiring assessment
Vision-Related Injuries
Any injury from navigational difficulty due to visual impairment
Medication-Related Risk
Inadvertent use of medications that increase bleeding
Urgent Medical Evaluation Required For:
- Heavy or persistent bleeding not responding to local measures
- Fainting or loss of consciousness
- Severe weakness preventing standing or walking
- Blood in vomit (hematemesis) or black/tarry stools (melena)
- Significant head injury (internal bleeding concern even without visible external bleeding)
- Rapidly worsening symptoms of any kind
In any of these situations, the family was instructed to seek immediate medical attention at the nearest hospital, regardless of the time of day.
Recovery Timeline and Clinical Progression
Hermansky-Pudlak syndrome is a lifelong inherited condition. The goal of home care was never to “cure” HPS but to achieve improved safety and functional adaptation following the acute bleeding episode.

Family Education Program
Family education was an ongoing process. The distinction between trained professional care and untrained attendant support becomes particularly evident in a condition like HPS.
Bleeding Precautions Education
- Avoid unnecessary injury — but without restricting all activity
- Use gentle oral hygiene techniques — soft-bristled brush, no aggressive flossing
- Inform all healthcare professionals about HPS before any procedure
- Avoid medications that increase bleeding unless specifically approved
- Persistent bleeding requires medical evaluation — do not wait
Vision Support Education
- Maintain adequate home lighting in all areas
- Increase contrast around frequently used objects
- Keep household items in fixed, organized locations
- Ensure protective sunglasses are worn outdoors
- Use verbal cues rather than physical pulling in unfamiliar environments
Injury Prevention Education
- Avoid activities involving sharp tools — delegate cutting tasks
- No high-impact exercise or contact sports
- No unsupervised hazardous tasks
- Keep first-aid supplies accessible; family knows basic bleeding first-aid
- Emergency contact numbers displayed prominently
Clinical Outcome Summary
CLINICAL OUTCOME NOTE
Hermansky-Pudlak syndrome is a lifelong inherited condition. Home care therefore focused on bleeding prevention, visual safety, functional independence, and coordination of specialist follow-up — not on eliminating the underlying genetic disorder. The outcome reflected improved safety and functional adaptation within the realistic boundaries of a chronic condition.
Walking: ~210m → ~330m
Zero significant episodes in 12 weeks
Moderate → Minimal fatigue
Consistent use of coping strategies
Fully independent in all basic ADLs
Reduced anxiety, better preparedness
Remaining Challenges and Long-Term Care
Ongoing Needs
- • Regular hematology follow-up
- • Continued ophthalmology assessments
- • Lifelong bleeding precautions
- • Vision support as a permanent feature
Long-Term Monitoring
- • Awareness of potential subtype-specific complications
- • Periodic screening as recommended
- • Pre-procedure planning for all interventions
- • Genetic counseling considerations
Key Clinical Learnings
1. Normal platelet counts do not rule out bleeding risk in HPS. The bleeding tendency is functional, not quantitative. Healthcare providers and families must understand this distinction to avoid false reassurance.
2. The “minor injury” that triggers hospitalization often reveals a gap in preparedness, not a new disease. In Ananya’s case, the oral injury was minor, but the family’s response plan was insufficient. Home care helped build a more robust framework.
3. Vision impairment in HPS affects safety far beyond reading. It impacts mobility, fall risk, craft work capacity, and confidence. Home adaptations must address the full functional spectrum.
4. Recovery from blood-loss anemia is gradual and must be monitored, not assumed. Fatigue improved over weeks, correlated with hematologist-directed lab follow-up.
5. Patient education about communicating HPS to all healthcare providers is essential. Dental procedures, minor surgeries, and even routine blood draws can become dangerous if the provider is unaware.
6. Home care for rare diseases requires condition-specific training, not generic nursing skills. A nurse who understands HPS monitors different things and provides different education. This specificity is what makes specialized nursing services valuable.
Frequently Asked Questions
Hermansky-Pudlak syndrome is a group of rare inherited disorders that can cause platelet dysfunction, reduced pigmentation, and visual problems. Certain forms may also affect other organs such as the lungs (pulmonary fibrosis), intestines (inflammatory bowel disease), or kidneys. It is caused by mutations in genes responsible for lysosome-related organelles and is inherited in an autosomal recessive pattern.
The platelets in people with HPS may have impaired storage granules (dense granules), which normally contain substances like ADP and serotonin essential for normal platelet aggregation and stable clot formation. Without these granules, the initial platelet plug is unstable, leading to prolonged bleeding even when the platelet count appears normal. For related reading, see our guide on haemophilia causes, symptoms, and treatment.
Yes. Many individuals with HPS have reduced pigmentation of the retina and iris, associated with visual problems including reduced visual acuity, nystagmus (involuntary eye movements), and light sensitivity (photophobia). These are typically present from early life and are stable rather than progressive, but can significantly affect daily functioning.
Minor bleeding should be managed according to the patient’s individualized medical plan, typically including firm, sustained pressure. However, persistent, heavy, or unusual bleeding requires prompt medical evaluation. Caregivers should never assume bleeding will stop on its own in HPS. If bleeding does not respond to standard first-aid within a reasonable timeframe, or involves critical sites, immediate emergency care should be sought.
Not necessarily. Appropriate physical activity can support general health and psychological well-being. However, activities with high trauma risk — contact sports, high-impact exercise, or activities involving sharp objects — may need to be avoided or modified. In Ananya’s case, gentle strengthening, walking, balance exercises, and light stretching were all appropriate and beneficial.
Regular eye assessments help monitor visual function and identify appropriate strategies or aids for daily activities. While the visual impairment in HPS is typically stable, the functional impact can change. An ophthalmologist can also rule out other causes of visual changes and ensure home adaptations are appropriate.
The surgical and hematology teams should be informed about HPS well in advance so an appropriate bleeding-management plan can be developed. This may include pre-operative medications, avoidance of certain anesthesia drugs, careful surgical technique, and close post-operative monitoring. This applies to dental procedures and minor interventions as well. The patient or family should carry medical documentation about HPS.
HPS is an inherited genetic condition and is not currently curable. Management focuses on preventing bleeding complications, supporting vision, monitoring for organ involvement when relevant, and maintaining quality of life. With appropriate precautions and medical follow-up, individuals with HPS can lead functional and fulfilling lives.

Educational Learning Points
Hermansky-Pudlak syndrome is a rare inherited disorder that can affect platelet function and vision simultaneously.
Bleeding may occur because of platelet dysfunction even when the platelet count is not severely reduced.
Patients should inform all healthcare professionals about the condition before any procedures or invasive treatments.
Persistent or significant bleeding requires prompt medical assessment regardless of how minor the triggering injury appeared.
Visual impairment in HPS can significantly affect mobility, household safety, and occupational functioning beyond just reading difficulty.
Appropriate lighting, visual adaptations, and protective eyewear can substantially support daily functioning in patients with photophobia and reduced acuity.
Home nursing can systematically monitor bruising, bleeding, fatigue, medication adherence, and appointment compliance between specialist visits.
Nutrition and laboratory follow-up are critically important when a patient is recovering from blood-loss anemia at home.
Care plans should be individualized according to the patient’s specific HPS subtype and associated organ involvement, as the clinical spectrum varies significantly between subtypes.
